摘要:
通过对黄土某事故建筑物进行现场勘查,并进行沉降观测,在对该建筑物地基土性指标比对时,发现该建筑物地跨灞河Ⅲ级阶地和低级黄土塬两个不同的地貌单元.通过对厂房破坏机理进行分析,发现由于低级黄土塬地基土的工程性能明显优于灞河Ⅲ级阶地地基土,致使厂房沿分界线产生较大的剪切变形,地基被雨水浸泡后,加速了建筑物地基黄土的不均匀湿陷沉降,最终导致建筑整体破坏
Abstract:
By analyzing the scene investigation and the settlement observation of some accident building in Xi′an, the article has pointed out the reason of the accident project. Since the building is located across two different landform unit and the foundation design was unreasonable, the integral decline of the accident building has been accelerated by the rain water. Since the Loess Plateau soil project of the Low-level foundation is better than Grade Ⅲ terraces Bahe foundation ’s the workshop was thus caught in a larger deformation along the border line. The article shows that the rain soaked the ground and accelerated the building of uneven collapsible loess foundation settlement, leading which eventually led to the destruction of the whole building
